The present invention relates to a packeting machine intended chiefly for packeting match-boxes but which can also be employed for the packeting of other goods.

The machine is characterized by two cheeks rotatably mounted and movable in the directions to and from each other, between which cheeks the number of boxes intendedfor a packet is introduced, and bi which these boxes are rotated, during whic rotation the wrappin -paper is wrapped around said boxes. A er this has been done and the checks have stopped their, rotation, a support adjusts itself under the packet against which the packet is firmly held by a press-roll resting on the upper end of the wrapping-paper and which acts on the top of the said packet, whereby the cheeks can be so far moved apart that they come outside the side-edges of the wra ping-paper. After this, the first foldingown of the wrapper at the ends of the packet, against which ends the cheeks previously acted, is made by means of'a coupleof plates which,

as soon as they have come-down farenough, hold the packet firmlyrbetweenthemselves and remove the same to another place in the machine, where the wrap er at each end of the packet is folded in om the sides and from underneath. V I A machine constructed in accordance with this invention is shown in the accompanying drawings, wherein v Figure 1, is a side elevational view of the machine; Fig. 2, is an end elevational View thereof, and Fi 3 is aplan.

In Figs. 1 and 2 are shown the two cheeks 1 and between them a number of matchboxes, in the form of a packet 2, which lies about in the middle of the machine. As,

however, the devices existing on one side of the middle for the purpose of acting on the one cheek resemble, or are analogous with,

the devices existing for the same purpose on the other side of the middle only those existing on the one side arefldescribed and shown.

In order to put each 'cheek' into the movement desired, the axle 3 of the same is placed in connection with the continuously rotating driving-axle 4 of the machine by means of a suitable gearing consisting preferably of cog-wheels 5, 6, 7, 8 and 9, of which the wheel 5 is arran ed on the driving axle, and the wheels 6 and 7 on intermediate axles 10 and 11 which are journaled in the same bearings' 12 which support the axle 3. The pinion 9 on the axle 3 is rovided on the whole of its circumference wlth teeth but the wheel 8 which engagesin the same has only a part of its circumference toothed, and this part is provided with so many teeth as correspond to the number of teeth on the pinion in order that this latter may be turned around once while the teeth on the wheel 8 are engaged in the same. After the pinion has completed a revolution and consequently,

the cheek 1, has also been rotated once, rotation of the latter is temporarily stopped by a cam 13-attached to the axle 11 at one side of the wheel 8, said cam having a sectorshaped cam-surface, corresponding to that part of the circumference of the wheel 8 which is not toothed, and intended to enter into .a corresponding recess 14 in a disk 15 arranged on one side of the pinion, by which means the axle 3 is prevented from rotating, while the axle 11 completes that part of a revolution which corresponds to the untoothed part of the circumference of the wheel 8- 1 Thesecond or rectilineal movement of the check 1 is brought about by-a displacement of the axle 3 on which, for this purpose, .there is attached a collar 16 with a groove 17 all around it into which enter the prongs of a fork 18, attached to a rod 19 which 15 displaceably arranged in the-bearings 12. The

, ork 18 1s provided with a projection with a roller 20 which enters into the groove 21 in a drum 22 attached to the axle 11. The groove 21 has such a shape and such a position that the axle 3 with the cheek L is dis placed forward and backward during that period when the cheek does not rotate. The pinion 9 and the disk 15 are evidently so arranged on the axle 3 that, at the displacement of the latter, they are not moved out of their place and, besides, cannot be rotated on the axle.

The matchboxes which are to be packeted are, by means of a. device which does not lie belong to this invention, fed to a lace which is situated immediately under t e opening between the cheeks 1 into a special art 23 which, in section, is preferably angu ar and is carried by an arm ,24 attached to a rotatably journaled axle 25, by means of whlch the part 23 can be raised from its lower position to the opening between the checks 1 and there place that number of boxes which are to form a packet. As soon as theboxes have come into this position the cheeks approach each other so much that all the boxes are held securely between them, after which the part 23 immediately descends to its lower position in order to receive the boxes which are required for the next packet. In order that that end surface'of each cheek which lies against the boxes may be in a certain degree yielding, so that even hard packed boxes, which are thicker than those not packedso hard, can be held fast without inuring the matches, the end of each cheek consists of aplate 26 which is attached to pins 27 acted upon by springs 28 which press the plate outward. \Vhile the boxes are being held fast between the cheeks, then (by. means of an arrangement described below) from a magazine 29 for wrapping-paper, the top sheet or leaf is carried forward therefrom so far above the checks that the front edge of, the sheet at each side of the same comes into a clamp arranged on each check,

which clamp conslsts of an arm 30 attached to a pin 31 which extends below the under side of the cheek and which is acted upon by a spring 32 which tends to draw down the arm into arecess in the cheek. :When the paper is fed onward to the cheeks each clamp is open, because the free end of a lever 33 which is acted upon by a cam 34 on the axle 11, lies againstthe lower end of the pin 31 and lifts the same. After the paper has come into the clamps, it is clamped fast by the lever 33 descending and the springs 32 drawing down the arms 30 after which, the checks, as has been stated above, are rotated once. When this is being done the paper is held close to the packet by means of a presser device, for exam le, a roller 35 carried b arms 36arrange on an axle 37, and witi the help of an arm 38 acted on by a cam 39.

When the revolution mentioned above is completed and the-cheeks have stopped the roller 35 then resting against the end of the wrapper and pressing the same against the packet, there .comes forward against the 'underside of-the packet a supporting plate 40 arranged on the end of an arm 41 which is attached to an axle 42 and which, with the help of an arm 43 is acted on by a cam 44. The plate 40 against which the packet is pressed by the roller 35, serves to support the said packet when the, cheeks, after the rotation is ended, are withdrawn in the long-itudinal direction of the axles 3 .away from down of the-wrapper at the ends of the packet may be brought about. In order that the displacement of the cheeks .may take place without the wrapper bein injured by the clam s these are opened a ittle on this occasion y the aid of the levers 33 and the cams 34 so that the paper can lide out .of said clam and then the chee s: are displaced so ar that those surfaces of the plates 26 which are't'urned toward the packet come outside the edges of the wrapper. It is clear that during this displacement of the checks the clamps must be open until the ends of the arms 30 have come outside the edges of the pa er, and for this reason the surface of each 0 the arms 33 against which the lower end of the pin 31 lies, is so broad that the clamp is kept open for a sufiicient len h of time during the displacement of the c eeks.

The firstfolding-down of the wrapper at the ends of the packet is done with the help of two folding plates 45 which, when the folding shall take place are situated above the packet, one at each of its ends, and each of which plates is attached to one end of a rod 46 which is displaceably arran ed in a sleeve 47 rotatably s uspended and w ich rod at the other end is articulated to a lever 48. This lever is acted on by a oved drum 49 mounted on an axle 50 which, by means of a conical gearing 51, 52, receivesits motion from the drivlng-axle 4. On the axle 50 there is mounted a cam 53 against which rests a roller 54 on a cross-piece 55 which connects two rods 56 whichare displaoeably arranged each on one side of the magazine 29, and-which above are connected by means of a cross-piece 57 on which the sleeves 47 are rotatably suspended. The folding plates 45 and the rods 46 receive, as will be understood from the above, partly an up and down movement from the cam 53 and partly a movement in the longitudinal direction of the rods from the grooved drum 49. The downward directed movement takes place as soon as those ends of the cheeks which are turned toward the packet have come outside the edges of the wrapper,

the plates 45 then folding down 'thelwrapper against the ends of the packet which while this is bein done is pressed against the supporting plate 40 by the roller 35.

When the folding plates 45 descend to their lowest positionthe packet will be held fast between them, as the distance between the plates when they are in a raised position is somewhat less than the distance between the ends of the acket, and as, besides, the plates 1 are attache to the free ends of-the comparatlvely long rods 46 whereby a certain elasticity in these latter can be utilized, so that,

the packet is held fast by the lates when these have descended to their owest position. Immediately hereafter the pressure i 29-, the paste-holder 60 at once descends in order to lift up the next paper so that this latter will be lifted so early thatthe clamp jaw 66 will be sure tocome underneath it during the return movement of the rods 46 and 6 The pa er pile in the magazine 29 rests on a plat orm 71 which is (movable up and 'down in said magazine and which-is sup-- .30

Inamacbine of thecharacter described, =the combination with a pairofpheek' plates forholding articles to be wrapped, of means seem? of the roller 35 a ainst the packet ceases and the rods 46 are isplaced to the right (see Fig. 1) and in doing so they bring with themselves the packet held fast between 5 them, in order to afterward place said I packet on a table or other sup ort 58. During; this movement to the rig t, the rods 46 are acted on by the cam 53 30 that the packet with respect to its position vertically comes into its place on the table, and as soon as this has taken place, there comes against the upper side of thepacket a roller, or the like, 59 which retains the packet against the table whereupon the folding plates directly afterward rise in order to be carried by the grooved drum 49 and the lever 48 back to the position, shown in Fig. 1, above the cheeks l. The completion of the folding oi a packet which has been moved to the table '58 under the roller 59 is attained by a device which does not form part of this invention.

While the folding plates 45 descend against, and hold fast a packet, thereafter move this and then return to their original 7 position, the bones intended tor the next packet are placed in positionbetween the cheeks, and the topmost sheet in the magazine 29 is removed therefrom to the cheeks.

' In order that it may be possible for the boxes to be raised into their position, the supporting-plate 4:0 is brought back toward the axle 11 and lies against it when the boxes are'raised by the part 23, which takes place as'soon as the acket between the plates has been carried by these a suficiently great distance from the checks. The boxes are thereafter pressed firmly between the cheeks and the part 23 descends, as described above,

To remove the top sheet from the magszine 29 to the checks, the following devices operated After a packet has been moved to thetable 58 b the folding plates 45, a paste- ,holder 60, w ich is movable in an up and down direction, and is arranged above that side of the paper-magaiine '29 turned to ward the cheeks and in the bottomof which holder there are openings for the ressing out of the paste on its under-side, escends ,toward the topmost sheet after which the holder 60 once more ascends and in doing so lifts that part of the sheet onwhich the paste has been put as well as theadjacent part of same sheet. The holder, 60 is carried b rods 61 which are displaceably arrang one on each side of the paper-ma 8:

. nine 29 and which below are connected y means of across-piece 62 with a roller 63 which lies against a cam 6t arranged on the axle 50 by which cam the holder 60 is vertically reciprocated. I

The above mentioned lifting of. the top 1 sheet can be facilitated by arranging by the side otthe holder an air-chamber 65 65 which is in connection with a suction appa ratus and in whose bottom, which is on a level with the bottom of the holder, there 7 are arranged suitable openings so that at the upward movement of the holder the paperwill be lifted by the aid of the suction, device too. That edge of the paper which is turned toward the cheeks is lifted so early that it is in a lifted position for the opportunity to enter under the lifted paper during the return movement of the plates. Each clamp 'aw' 66 extends from the one end of a ro 67 the other end of which is connected with that part which supports the end of the rod 46 and is acted on by the lever 48., The rod 67 which is drawn by a spring 68 in the direction toward the rod 46, is prevented by a roller 69 connected with the magazine29 from. being lifted by the spring 68 more than to a certain height, so that theiclamp-jaw 66 may be sure of coming in nnderthe lifted paper. W hen the lates t5, thereafter are moved down by t e rods a6 and fold down the wrapper at the ends of the packet, a clamp jaw 70 arranged on each rod d6 descends to-- ,ward the clamp-jaw 66, whereby the paper is clamped between them and is then ressed down somewhat, so lthat it is carrie away from the underside oi the holder 60 and thus, too, from the air-chamber 65 in which the suction has now ceased. The clamping of the L aper between the jaws 66 and 76 thus ta es place simultaneously with. the folding down of the wrapper at the ends ot the packet, and it is plain that when the acket is thereafter moved away, which is rought about by the displacement of the rods 46 a the paper which is clamped between the jaws will be wn out of the magazine in the direction toward the cheeks 1 between which, during that time which is required for the removal of a packet from its position between the checks to the table 58, the boxes for the next packet have come and have been pressed between the cheeks, and the clamps of these latter have been opened to receive and immediately catch the edes of that paper which has 'ust been carri e forward to them. When t e plates at are thereupon lifted m the packet which has been moved to the table 58, the

jaw 70 is lifted from the jaw 66 so that these, on their return 'moyement, cannot disturb that paper which is now retained by the cheeks and which, during the return tween the cheeks. As soon as a paper has Inovement mentioned, is wrapped around the boxes which have last been-placed befor placing a wra per blank about said articles, a pair of f dlding plates to fold the end flaps of said wrapper blank against the articles, and means for moving said folding plates thereafter to move the same horizontally, whereby the plates convey the partially completed package outside the machine, substantially as described.

In a machine of the character described, the combination with a pair of cheek plates for holding articles to be wrapped, of means for placing a wrapper blank about said articles, a supporting plate movable into a position under the articles to support the same while the articles are stationary, means to move the cheek plates axially away from the articles, a pair of folding plates, and

means to move the folding plates vertically to fold the end flaps of the wrapper and horizontally to conve the partially completed package outsi e the machine, substantially as described.
